Active clinical trials for "Postpartum Hemorrhage"

The investigators prepared a novel study of tranexamic acid (TXA) designed to estimate the quantity of blood loss in women undergoing elective repeat cesarean deliveries. This is the first trial to utilize a prophylactic dose of TXA prior to incision followed by a subsequent prophylactic dose at placental delivery in obstetric patients undergoing scheduled cesareans. The purpose of this study is to quantify blood loss during uncomplicated repeat cesarean deliveries with and without TXA. The central hypothesis is that TXA administration reduces blood loss and fibrinolysis in women undergoing repeat cesarean sections.

Insufficient uterine tone resulting in atony can potentiate hemorrhage and adverse outcomes for the parturient. Oxytocin is the first pharmacologic agent used, followed by methylergonovine, carboprost, and misoprostol. The American Congress of Obstetricians and Gynecologists (ACOG) recommends the sequential use of oxytocin, followed by methylergonovine, carboprost, misoprostol, then surgical intervention for cases of refractory uterine atony. Many studies have examined the effect and dosage of intravenous uterotonics, including oxytocin. Although there are anecdotal reports of using intravenous bolus or rapid infusion of methylergonovine, no randomized trial has compared efficacy and side effects of these two routes of administration. Investigators hypothesize that intravenous methylergonovine reduces the time to adequate uterine tone (the tone at which the uterus is adequately contracted to prevent atony after delivery of neonate), decreases the total dose of methylergonovine to contract the uterus, and therefore produces fewer side effects of hypertension, nausea, and vomiting. Reducing the time to achieve adequate uterine tone is likely to decrease postpartum hemorrhage.

The Millennium Development Goal of reducing the maternal mortality ratio by 75 % by 2015 will remain beyond our reach unless we prioritize the prevention and treatment of postpartum hemorrhage(PPH) in low-resource countries. Consequently, the administration of uterotonic drugs during cesarean section (CS) and in the third stage of labor for vaginal delivery has become essential to diminish the risk of PPH and improve maternal safety. Oxytocin is regarded as the gold standard uterotonic agent but only has a half-life of 4-10 min; therefore, at cesarean section oxytocin must be administered as a continuous intravenous infusion to attain sustained uterotonic activity throughout the surgical procedure and immediate postpartum period. Misoprostol is a prostaglandin E1 analog proven in several randomized controlled trials to be effective in preventing PPH because of its strong uterotonic effects. In addition, misoprostol is inexpensive, stable at room temperature, and easy to administer. Misoprostol has been broadly studied in the prevention and treatment of PPH after vaginal delivery; however, its use in conjunction with CS has not been investigated as much. The buccal route is recognized as having the greatest benefit due to its rapid uptake, long-acting effect, and greatest bioavailability compared with other routes of misoprostol administration. Carbetocin is a long-acting synthetic analog of oxytocin that can be administered as a single-dose injection; intravenously administered carbetocin has a half-life of approximately 40 min. A single intravenous bolus of carbetocin produces a tetanic uterine contraction within 2 min and persists for an average of 60 min following injection. The aim of this study was to compare the effectiveness of combined buccal misoprostol and IV tranexamic acid (TA)with intravenous carbetocin for prevention of PPH in patients with risk factors during cesarean section.

This study seeks to determine if the using tranexamic acid prophylactically at caesarean section will prevent postpartum haemorrhage which is a major cause of maternal mortality in Zimbabwe and globally.

Sublingual misoprostol produces rapid peak concentration and is more effective than oral misoprostol for prevention of excessive postpartum bleeding. The study hypothesis was to test whether women receiving sublingual misoprostol for prevention of postpartum hemorrhage have 30 ml less average blood loss than women receiving oxytocin, the standard of care for prevention of postpartum hemorrhage. We conducted a Double blind randomized controlled trial of .652 consenting, eligible pregnant women admitted to the labor room of the teaching hospital at J N Medical College, Belgaum, India. Women participating in the study were assigned by computer generated randomization to receive the study medications and placebos within one minute after clamping and cutting the umbilical cord. We also looked at the drugs effects on postpartum blood loss at or above ≥500 ml (considered hemorrhage), and the percent of women experiencing more than a 10% decline in haemoglobin, and reported drug side effects.

Increased blood loss after vaginal or cesarean delivery is one of the top causes of maternal complications. Oxytocin is a common medication given to mothers by IV or an injection to limit the amount of blood loss after delivery. The investigators do not know the best time after delivery that oxytocin should be given. This research is being done to find out if starting the medication oxytocin right after the baby is born or after the placenta comes out decreases the amount of blood lost after birth when we delay cord clamping after birth.

In this study, our aim was to evaluate the effectiveness of prophylactic tranexamic acid use after vaginal delivery in pregnant women aged 18-45 years and 34-42 weeks according to the risk of postpartum hemorrhage.

Objective: To investigate the effect of A glove-loaded Foley's catheter tamponade versus stepwise uterine devascularization on blood loss during cesarean section (CS) in patients with complete placenta previa.

The purpose of this study is to assess whether the administration of a low dose of tranexamic acid just after vaginal delivery can reduce the incidence of immediate postpartum hemorrhage, in women who receive a prophylactic administration of oxytocin.
